• Resumen

  • This Thesis includes a study of means by which the tendencies of deformation have been reconstructed in the lithospheric mantle of the Iberian Peninsula. We studied telesismic events recorded in broadband seismic stations of different network in two geologic domains of the Peninsula: the Variscan Massif and the Betic Cordillera. The measured trends of deformation have been compared with other geophysical parameters and they have been explained in geodynamic contexts related to the events that have forged the studied areas. The Iberian Peninsula and in particular the Gibraltar arc, constitute regions where many questions are still open. We have chosen the seismic anisotropy as instrument for the study because its structural origin can bring information on large-scale about the behaviours of structures on long scale and contribute to geodynamic and structural reconstructions. The calculated seismic anisotropy from SKS phases of teleseismic event is the instrument for the study of the upper mantle where the seismic anisotropy reflects plastic flow either active or frozen, depending on whether seismic waves penetrate the asthenosphere or remain in the lithosphere.
